HIDTB08-UNI-SC-SC Pepperl+Fuchs

Description

Product Name: HIDTB08-UNI-SC-SC Pepperl+Fuchs Power module

Product details:

The Pepperl+Fuchs HIDTB08-UNI-SC-SC is a termination board designed to interface with H-System intrinsic safety isolators. This board acts as a central hub, simplifying the wiring and installation process for industrial automation and process control applications, particularly in hazardous areas. The “08” in the model number indicates that it supports up to eight individual isolator modules.

Key features include:

• Universal Compatibility: This board is designed to accept a mixture of different I/O types, allowing for flexible system configuration. You can insert any compatible isolator into any of the eight slots.
• Integrated Terminals: It features fixed screw terminals for both the field-side (hazardous area) and control-side (non-hazardous area) connections, making wiring straightforward and secure.
• HART Communication: The board is equipped with a HART cordset, which allows for easy interconnection to a separate HART communication board. This enables digital communication alongside the analog signals.
• Fault Indication: It includes a volt-free contact output for fault indication. This relay contact can signal faults related to the power supply or individual modules, providing a clear and reliable warning.

Product Parameters

• Number of Modules: 8
• Nominal Voltage: 24 V DC (with consideration of the rated voltage of the used isolators)
• Fusing: 2 A per 8 modules
• Power Dissipation: $\le 500\text{ mW}$ (without modules)
• Reverse Polarity Protection: Yes
• Degree of Protection: IP20
• Ambient Temperature: −20 to 60∘C (−4 to 140∘F)
• Storage Temperature: −40 to 70∘C (−40 to 158∘F)
• Mounting: Standard 35 mm DIN mounting rail (according to EN 60715)
• Housing Material: Polycarbonate, 10% glass fiber reinforced
• Dimensions (W x H x D): Approximately 150 x 200 x 163 mm (5.9 x 7.9 x 6.42 inches), including module assembly
• Weight: Approximately 630 g

Product Advantages

• Simplified Installation: The universal slot design and clear, fixed screw terminals significantly reduce the complexity of wiring and system setup.
• High Flexibility: The ability to mix and match different I/O modules on a single board allows for a highly flexible and space-efficient solution in control cabinets.
• Enhanced Safety and Reliability: Built-in features like fault indication, reverse polarity protection, and robust housing ensure safe and reliable operation, especially in demanding industrial environments. The design facilitates quick and reliable installation on a DIN rail.
• HART Support: The inclusion of HART communication support makes the board compatible with modern smart field devices, enabling advanced diagnostics and asset management.

Precautions

• Isolator Compatibility: Always ensure that the specific H-System isolators you are using are compatible with this termination board.
• Power Supply: The nominal voltage is 24 V DC, but you must consider the rated voltage of the individual isolators. Pay attention to the voltage drop across the board’s internal series diode.
• Wiring: Connect the field-side wires to the blue terminals and the control-side wires to the black terminals to prevent wiring errors and maintain safety standards. The core cross-section for the screw terminals should be between 0.25 and 1.5 mm².
• Environment: While the board has an IP20 rating for protection, it is primarily designed for installation inside a control cabinet to protect it from dust, moisture, and other environmental factors. Adhere to the specified ambient temperature range to ensure proper operation.

Product Applications

The HIDTB08-UNI-SC-SC is primarily used in industrial automation and process control applications where a safe and reliable interface is needed between control systems (like a PLC or DCS) and field devices located in hazardous or explosive areas.

Typical applications include:

• Chemical and Petrochemical Plants: Interfacing sensors and actuators in areas with flammable gases or vapors.
• Oil and Gas Industry: Monitoring and controlling equipment on drilling rigs, refineries, and pipelines.
• Pharmaceutical Manufacturing: Ensuring safe operations in clean rooms and processing areas.
• Food and Beverage Production: Automating processes in environments where explosive dust or vapors may be present.
